Mini library steps out of reclaimed mahogany

We have a little cabin and I'm installing a mini library so I also need to make steps to reach the upper shelves. I plan to use reclaimed mahogany for the steps, and I've hit a snag with the folding top platform. It's going to be supported by a 10mm brass rod, and I'm struggling to cut threads on it. Is brass typically harder to thread than steel? I've chamfered the end of the rod, but maybe it needs more. Any suggestions on getting a clean thread or any other approach I should explore?

Brass can be fussy if what you're using isn't sharp enough or if you're not using enough cutting oil. Maybe try slowing it down a little? Like try backing off every quarter turn to clear chips.
 
Try using a die meant for non-ferrous metals and make sure you're not forcing it. Chamfer it a bit deeper and use good cutting oil, then ease into it with short turns and back it off often.

Thanks! Are there brands or types you'd recommend for threading brass? And how deep should the chamfer be to avoid tearing the threads?
 
Brass is easier to thread than steel, but 10mm can be quite thick for hand threading. Make sure to use cutting oil or WD-40, align the die perfectly square at the start, and take light passes. Remember to back off half a turn after each complete turn to break the chips.
